Cogeneration plants are units that simultaneously produce electricity and useful heat from the same fuel. In such plants different components (prime movers, pumps, steam generators, etc.) are combined in order to meet electricity and useful heat loads requirements. The trend in cogeneration is to move toward more efficient and often more complex plants, so that their design requires an expressive amount of engineering expertise and time. In this work, it is presented an expert system prototype to support engineers in the conceptual and preliminary design phases of natural gas cogeneration plants, considering the loads related to electricity and saturated steam as design requirements. The prototype consists of a knowledge base composed of rules, object-oriented, component technical information and procedural functions. It is able to provide different designs for the same requirements, each of them containing plant diagram, components specifications and sizing, and explanations for each prototype decision. A case for a plant with demands as 15MW of electricity and 30 t/h of saturated steam at 8bar is presented.
